During night one of the finale, the 12-year-old ukulele player — dubbed "the next Taylor Swift" by Simon Cowellway back in her audition — closed out the show performing her flawless original song Clay!

Not only did the little songstress slay her performance of her original song Beautiful Thing, which she wrote for her sister, but VanderWaal was praised by the judges, who gave her a standing ovation.

Heidi Klum called the soon to be teen "one in a million" while Howie Mandel one-upped Simon by saying she'll be "bigger than Taylor Swift. I predict you are the biggest star to ever come out of this show."
